Ship navigation is the process of determining a ship's position and planning its course to reach a destination safely. Navigators use various tools and techniques, including maps, compasses, and GPS technology, to track the ship's location and avoid obstacles like rocks, shallow waters, and other vessels. Modern navigation also involves understanding weather conditions and tides, which can affect a ship's journey. Additionally, navigators must be familiar with maritime laws and regulations to ensure safe passage through different shipping lanes and ports. Effective navigation is crucial for the safety of the crew and the ship itself.
